MAGNETIC RAPID S'I'ZlliIPING DEVICE.

Application filed June 18, 1923. Serial No. 646,1a6.

T 0 all whom it may concern:

Be it known that I, BENJAMIN BORN- srniN, a citizen of the UnitedStates, and resident of Shamokin, in the county of Northumberland andState of Pennsylvania, have invented certain new and useful Improvementsin Magnetic Rapid Stamping Devices, of which the following is aspecification.

This invention relates to stamping and marking devices and for its mainobject to provide a stamping device in which the exchange of the types,signs, markings, etc. is extremely simple and rapid and new combinationsof such. markings may be made with great ease and facility.

Another object of my invention is to provide a device of the mentionedcharacter which is adapted to receive a great variety of diverse signsand markings besides the regular types used in similar apparatus.

till a further object of this invention is to provide a rapid stampingdevice where the types and markings are held in their places by magneticforce only.

Other objects of my invention will be apparent as the specification ofthe same proceeds.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the same foreffecting the various results mentioned hereinbefore, reference is to behad to the following description and ac companying drawings.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiments of the sameare illustrated in the accompanying drawings, in which a Fig. 1 is aside 'elevational view of one embodiment of my device,

F ig. 2 is a front elevational view of the same,

Figs. 3 and 4: are detail views of portions of this embodiment of myinventions, while Fig. 5 is a side elevational view of anotherembodiment of this invention.

Referring now more closely to the drawings, the numeral 6 indicates themain body of my rapid magnetic stamping device, said body being in theform of a horseshoe and made of magnetized steel. The free ends7 and 8of said horseshoe magnet Where the magnetic attraction most stronglyreveals itself, are slotted as at 9 (Figs. 1 and 3), severalcorresponding slots being provided in both magnetic ends or poles 7 and8, being the north and south poles of said horeshoe magnet. My typeholders consist of soft iron bars 10, slidably fitting into the slots 9and adapted to be pushed therein simultaneously at both ends of myhorseshoe magnet in the longitudinal direction of said magnet frame. Thetwo magnet ends? and 8, or north and south, will immediately thereuponcounter magnetize the soft iron type holder bar 10 and firmly hold thesame in theirslots by magnetic attraction. The

type holder bar has a longitudinal slot 11;

provided therein into which fit the types or markings proper 12 and maybe retained therein by frictional or by any other suitable means. In;order to provide easy and convenient means for exchanging the typeholdersin my horseshoe magnet, the ends 13 of said type holders are madeto slightly project over and outside the end surfaces of the horseshoemagnet and any of the type holders may be gripped by said extensionsbetween the forefinger and the thumb of the user and pushed in place orremoved from slots 9. The side walls 14 of slots 9 will prevent thetransversal movement of the type bars, while a central raised portion 15fitting between the two sides of the horseshoe magnet will provide anadequate check against the longitudinal displacement of my type barsafter they have been pushed in their proper positions.

The markings proper 12 may be made of wood. type metal, rubber or of anyother suitable materials and may show types, signs, designs, straps orany other markings as the case may require and it is obvious that bytheir rapid exchange in the several slots 9 an easy and convenient meansis provided for an endless variety and combination of such markings.

For a convenient handling and use of my lighter and cheaper constructionbut the magnetic forces will be greatly weakened as against the horeshoeform and the magnetic frame Will also sooner loose its force ofattraction and requirea remagnetization. In this modification themagnetic bar 18 carries several slots 19 at its free end, into which litthe type bars 20 showing the exposed types and markings 21. A dowel pin22 may be provided for each such type bar, fitting into a hole in thesame and preventing its movement in any direction, while projecting endssimilar to those shown at 13 in Fig. 2, may be used for exchanging thetype bars in the manner described hereinbefore.

The advantages of my rapid stamping device may at once be seen when itis necessary to make a great many changes and markings either byresetting the types or by having separate frames for each combination ofmarkings, as it is now done in many industries. I have been using thesame in the shoe industry and have found it a great time saver in themarking of shoe boxes, both for the wholesale and retail trades. In themarking of shoe boxes many combinations of markings are often necessaryas for instance boxes may be markel: red-one strap, blue-one strap,green one strap, same colors two or more straps, etc. With my stampingdevice, one magnetic frame is only necessary, .while types and markingsor the elements of them may be carried on separate type bars easy to beplaced in said frame or to be removed from the same.

Having thu described. my invention, what I claim as new and want toprotect by Letters Patent of the United States, is

1. In a stamping device in combination, a magnetic member, slots acrossthe end surface of said member, type'bars of magnetic metals bearingsigns, types and markings at their exposed surfaces and removablyfitting into said slots, means to keep said bars in said slots inpredetermined positions,

and means for removing said bars from said slots.

2. A stamping device, comprising a magnetic frame of a horseshoe form,colinear pairs of slots provided in the two end surfaces of saidhorseshoe frame, type bars of magnetic metals fitting into said pairs ofslots and having their ends slightly projecting over the correspondingside surfaces of said magnetic frame, a raised central portion on saidtype bars fitting between the two arms of said horseshoe magnet andpreventing the longitudinal movement of said bars in said slots, typeand markings secured into the exposed surfaces of said type bars and ahandle on said magnetic frame.

Signed at New York in the county of New York and State of New York this15th day of June A. D. 1923.

BENJAMIN BORN-STEIN.
